Tried to resolve from these answers: https://discourse.hkvstore.com/t/interface-psr-http-message-requestfactoryinterface-not-found/3419/1 Reinstalled composer, replaced composer.phar with the last one and 1.10.16, cleared the cache, but nothing helped.

go to the folder where the files have been generated and try and run the command:composer update

@anonga thnx for answer, but result is

"composer" is not internal or external
command, executable program, or batch file.

Read Composer.
